摘要
本文提出了一种新的推进式求解方法,用显、隐MacCormack格式对定常超音速绕流进行了分区求解,本方法可用于流过任意形状的超音速身部流动。通过对钝锥超音速绕流的数值模拟,表明了此方法可以避开下游的影响问题,避免了推进法对亚音速区压力梯度的特殊处理。计算的结果与文献相吻合。
A new space marching method is given to compute supersonic flow fields surrounding a Blunt -Body body. The computations have been performed for flow conditions convesponding to an exensive series availabe of experimental surface pressures and heat-transfers.
